Blocking tech giamts?

I'm developing a study to research the extent to which blocking connections to tech gisnts (via the OS firewall) affects the User Experience (UX).

Has anyone developed a program that determines all the IP addresses owned by given coprorations? Bonus points if someone can point me to a graphical interface that might accompany the firewall to tell the user which corpoartion they were just blocked from connecting to.

If it's easy to setup, would you be interested to join the study? Connections to the giants over proxies like Tor are, of course, allowed (whether the connection is accepted is another story).

Looking forward to thoughts, suggestions and help. Thanks for reading.

I don't know of such program. The problem is hugely complicated, see, for example:

Quora: How can I obtain a list of IP addresses owned by a specific company?

Re: Blocking tech giamts?

Yes, thanks alcornoqui. I realized it might be difficult during the initial brainstorm. I've been able to amass a large database manually that I'm personally happy to start with. Pairing this with a firewall that asks a user for permission before the OS connects I think I can get very close to an ideal testing ground.

If anyone wants to take part feel free to contact.

Btw it seems quora don't respect Tor privacy:

You can add it to The Firebog!

Are you aware of the Pi-hole project? It's not exclusive to the Raspberry-pi at all.

Thankfully most have reasons to give the info. Ready for it?


Cloudflare:

IP Addresses:
IPv4: https://www.cloudflare.com/ips-v4
IPv6: https://www.cloudflare.com/ips-v6

Domains:
A large file apparently with over 3 million Cloudflare domains (Cloudflare have been said to control, by various means, 25% of the internet so noone should be surprised by this). As explained here (https://securitytrails.com/blog/explori … public-dns) a full list of domains is here (https://s3.amazonaws.com/public-data.se … mp.csv.bz2):
- because this list is so huge, would the best way be to onion route all DNS lookups then use ip addresses exclusively to block?



Google:

IP Address ranges:
https://www.gstatic.com/ipranges/goog.json

Domains:
https://whois.domaintools.com/domains.google (I'm doubting that this is a complete list)



Amazon:

IP Addresses:
https://ip-ranges.amazonaws.com/ip-ranges.json



Facebook:

IP Addresses and Domains:
https://ipinfo.io/AS32934
  - Site hides the full list with CSS so use HTML to find both IPv4 and IPv6

A domains list that (seems a tad outdated, see below):
https://raw.githubusercontent.com/jmdug … cebook/all



Microsoft:

IP addresses:
https://www.microsoft.com/en-us/downloa … x?id=53602



Apple:

IP Addresses and Domains:
https://ipinfo.io/AS714
  - Again this page (also above) uses CSS to hide the full IPv4 and IPv6 lists so use the HTML:

---------

If you find this info useful, feel free to share it around, but expect more here as I/we do more work on this list smile
